Default C. rotation, Inside out or outside in?

Any info or input on the different systems? Port outdrive rotating right ? or left? Starboard opposite.
Changing old Formula to C. rotation drives. Which side should I change??

Step hulls seem to like the props spining inward. Conventional Vees seem to like the props spinning outward.

Spining out is more traditional and the boat will work better in reverse.

Do a search for Prop Rotation, lots of threads on this issue.

We spin ours in and I believe that that is Fountain recommends. Tried them out and lost speed and handling. Now on my outboard cat we always ran them out.

Looks like port is going left. Majority rules.

Guess what, you should notice by now that everyone has a different opinion on this....thats caus it's slightly different on every boat....

Try it and see on yours.....the only REAL way to see what it does....even on the same boat make and model.....I have seen different performance issues
